DESIGN OFIMPROVEMENT TO MINIMIZE MOTION WASTE IN PRODUCTION OF HEADCASING PART AT PT. MULTI INSTRUMENTASI WITH LEAN MANUFACTURING APPROACH

摘要

Multi Instrumentasi is a manufacturing company that produces water meters. In producing water meters, one of the parts is the head casing. Head casing part consist of two types namely LF-1 and LF-2. Constraints experienced by companies are the inaccessibility of head casing production targets that can hinder the sale of water meters to consumers. For this reason, a proposal to improve the lean manufacturing approach is proposed to minimize the waste that occurs. The stage of the lean manufacturing approach is to identify the production process that occurs using the Process Activity Mapping and Value Stream Mapping. Furthermore, identifying waste that occurs using fishbone diagrams. After identifying waste, waste motion is found in the process of making head casing part with manual lathes. Subsequently, proposed improvements were made using the Single Minutes Exchange of Die (SMED) method. After the proposed improvement, in one month the company can save production costs of Rp 24.000.000 by comparing the existing production costs with after the proposed improvements.
